Syntax
Passive Voice (Typology)
Same operation, very different machinery across languages
The passive is a voice operation that promotes the patient to subject and demotes the agent — but languages mark it very differently. English uses periphrastic be + past participle; Japanese uses the morphological suffix -rare-; Mandarin uses the analytic bei-construction with adversative flavor; Tagalog has a four-way voice system in which "passive" is just one focus among many. Studying passives across languages reveals what is universal (a non-agent becomes the prominent argument) and what varies wildly (agent suppression, marking type, semantic flavor, productivity, even whether intransitives can passivize).

What the passive does
Take a transitive sentence. It has two participants: an agent (the doer) and a patient (the thing done to). In the active voice, English maps these to subject and object:
The dog bit the postman.
agent/SUBJ verb patient/OBJ
The passive promotes the patient to subject and demotes the agent. The agent can be expressed in an oblique phrase (the by-phrase) or simply dropped:
The postman was bitten (by the dog).
patient/SUBJ passive verb agent/OBL (optional)
Crucially, the event is the same — a single biting. What changes is informational packaging. The passive lets the speaker put the patient in topic position (where new sentences usually pick up old information) and leave the agent unsaid when it's irrelevant, unknown, generic, or politically inconvenient. "Mistakes were made."
Three things are happening simultaneously: (1) argument promotion — patient takes the subject slot; (2) argument demotion — agent loses the subject slot, becomes optional; (3) verbal marking — the verb signals that this rearrangement has occurred. Different languages do all three with very different machinery.
English: periphrastic be + past participle
English uses two words: an auxiliary (typically be, sometimes get) plus the past participle of the main verb.
Active: Mary wrote the letter.
Passive: The letter was written (by Mary).
The participle written is the same form used in the perfect (has written), which can confuse learners. The disambiguator is the auxiliary: has + past-participle is perfect; be + past-participle is passive. The agent appears in a by-phrase, marked with the preposition by.
English passives are productive — almost any transitive verb can be passivized — but ditransitives offer two options: "John gave Mary the book" passivizes as either "Mary was given the book" (recipient promoted) or "The book was given to Mary" (theme promoted). Other languages typically allow only one.
Japanese: morphological -rare- and the indirect passive
Japanese marks passive with the verbal suffix -(r)are-, attached directly to the verb stem. The agent is marked with the postposition ni (or sometimes kara):
Active: 犬が郵便配達員を噛んだ。
inu-ga yuubin-haitatsu-in-o kanda
dog-NOM postman-ACC bit
'The dog bit the postman.'
Passive: 郵便配達員が犬に噛まれた。
yuubin-haitatsu-in-ga inu-ni kam-are-ta
postman-NOM dog-DAT bit-PASS-PAST
'The postman was bitten by the dog.'
So far this is similar to English. But Japanese has a second passive — the indirect passive (also called the adversative passive) — that has no English equivalent. It applies to intransitive verbs and signals that the subject was adversely affected by an event:
太郎が雨に降られた。
Tarou-ga ame-ni fur-are-ta
Taro-NOM rain-DAT fall-PASS-PAST
'Taro got rained on' / 'Taro was adversely affected by rain falling.'
The verb furu "fall" is intransitive — there is no patient to promote. But Japanese still allows passivization, with the meaning that the subject suffers from the event. The passive isn't just argument-rearrangement; it carries a flavor of adverse experience.
Mandarin: the bei-construction
Mandarin uses an analytic strategy — a separate word, bei (被), placed before the agent:
Active: 狗咬了郵差。
gǒu yǎo-le yóuchāi
dog bit-PERF postman
'The dog bit the postman.'
Passive: 郵差被狗咬了。
yóuchāi bèi gǒu yǎo-le
postman BEI dog bit-PERF
'The postman was bitten by the dog.'
Classical Mandarin bei carried strong adversative semantics — the subject suffers. "我被欺騙了" (wǒ bèi qīpiàn-le, "I was deceived") is fine; "我被誇獎了" (wǒ bèi kuājiǎng-le, "I was praised") was traditionally awkward. Modern usage, under European-language influence, accepts neutral and even positive bei-passives, but the adversative undertone lingers.
Mandarin also has agent-less bei: "信被寄了" (xìn bèi jì-le, "the letter was sent"). And it has a longer construction bei + agent + gěi + verb that some grammarians treat as a separate passive type. The system is grammatically simpler than English (no participle morphology) but semantically richer (adversative meaning baked in).
Tagalog: the symmetrical voice system
Tagalog and most Philippine languages have something quite different — sometimes called symmetrical voice, the Philippine-type voice system, or historically just "focus." Instead of an active/passive contrast, there are four (or more) voices, all morphologically marked, none clearly basic:
Actor voice: Bumili ang lalaki ng isda sa tindahan.
AV.bought TOP man OBL fish LOC store
'The man bought a fish at the store.'
Patient voice: Binili ng lalaki ang isda sa tindahan.
PV.bought OBL man TOP fish LOC store
'The man bought THE FISH at the store.'
Locative voice: Binilihan ng lalaki ng isda ang tindahan.
LV.bought OBL man OBL fish TOP store
'The man bought a fish at THE STORE.'
Benefactive voice: Ibinili ng lalaki ng isda ang bata sa tindahan.
BV.bought OBL man OBL fish TOP child LOC store
'The man bought a fish FOR THE CHILD at the store.'
Each voice puts a different argument in the privileged slot marked by ang (the topic/pivot). Crucially, none is the "default" — all four are equally productive, equally common, and equally morphologically marked. This is why most typologists no longer call the patient voice a passive: passives by definition are marked alternatives to an unmarked active, and Tagalog has no unmarked baseline.
Cross-linguistic comparison
| English | Japanese | Mandarin | Tagalog | German | Latin | |
|---|---|---|---|---|---|---|
| Marking type | Periphrastic (be + ptcp) | Morphological (-rare-) | Analytic (bei) | Affixation (-in-/-an/i-) | Periphrastic (werden/sein) | Morphological (-r endings) |
| Agent phrase | by-phrase | ni-phrase | bei NP | ng-phrase (oblique) | von / durch | ablative + ā/ab |
| Adversative semantics | No | Yes (indirect passive) | Yes (classical) | No | No | No |
| Passive of intransitive | No | Yes (indirect) | No | N/A | Yes (impersonal) | Yes (impersonal) |
| Stative vs dynamic split | Context-dependent | Context-dependent | Context-dependent | N/A | sein vs werden | Context-dependent |
| Status of "active" | Default, unmarked | Default, unmarked | Default, unmarked | One of several voices | Default, unmarked | Default, unmarked |
| Productivity | High (most transitives) | High | Lower (favors adversative) | All voices fully productive | High | High |
The table flattens nuance — every language has restrictions and idiosyncrasies — but the patterns are real. English and German share a periphrastic strategy; Japanese and Latin share a morphological one; Mandarin alone has an analytic dedicated word; Tagalog stands apart entirely.
Worked example: passivizing one event in five languages
Consider the event: a child opened a door. Here's how each language packages it actively, then passively:
| Language | Active | Passive |
|---|---|---|
| English | The child opened the door. | The door was opened (by the child). |
| Japanese | 子供がドアを開けた。 kodomo-ga doa-o ake-ta | ドアが子供に開けられた。 doa-ga kodomo-ni ake-rare-ta |
| Mandarin | 小孩打开了门。 xiǎohái dǎkāi-le mén | 门被小孩打开了。 mén bèi xiǎohái dǎkāi-le |
| Tagalog (PV) | Binuksan ng bata ang pinto. (patient = ang pinto) | (no separate passive — patient voice is the same form) |
| German | Das Kind öffnete die Tür. | Die Tür wurde (vom Kind) geöffnet. (dynamic) Die Tür ist geöffnet. (stative) |
Notice that Tagalog has nothing extra to do — the "passive-like" reading is just one of the basic voice options, available without any added morphology. German has two passives and forces you to commit to dynamic vs stative. Mandarin's bei works fine here because opening a door is neutral, but would feel marked for joyful events.
Voice variants and relatives
- Middle voice. Found in Greek, Sanskrit, Latin, Romance reflexives. The subject is both agent and affected — "the door opened" (English uses an unaccusative; Spanish uses se: la puerta se abrió). Middle voice blurs into passive in some languages.
- Antipassive. The mirror of passive in ergative-absolutive languages: the agent becomes the prominent argument and the patient is demoted. Common in Mayan, Inuit, Australian languages.
- Impersonal passive. No promoted subject; agent suppressed. German "Es wurde getanzt" (literally "It was danced" = "There was dancing"). Latin and Polish allow this freely.
- Get-passive. English alternative: "He got fired." Often more colloquial, often with adversative or unintended-event flavor — "He was fired" is neutral, "He got fired" suggests bad luck or initiative.
- Adjectival passive. Stative: "The door is closed." Behaves like an adjective (gradable: "very closed"; with become: "became closed"). Distinct from verbal passive in syntactic tests.
- Pseudo-passive (prepositional). English allows "The bed was slept in" — the prepositional object is promoted. Most languages don't allow this.
- Long vs short passive. Long = with by-phrase ("by Mary"); short = without. Across languages, short passives are dramatically more frequent than long ones — agent omission is the main pragmatic motivation.
Why passive typology matters
- Universal vs language-specific. The passive is a probe for what UG-style universals look like — patient promotion appears widely, but the marking and restrictions vary, suggesting the universal is functional, not formal.
- Information structure. Passives are a primary way languages let speakers control topic and given/new. Studying them clarifies what discourse structure looks like cross-linguistically.
- Acquisition order. Children acquire active before passive in every language tested, but the gap varies — English children master full passives around age 5; Sesotho children much earlier, because passives are far more frequent in their input.
- Aphasia and processing. Broca's aphasics struggle disproportionately with reversible passives ("the boy was hit by the girl") — a classic finding that supports syntactic-deficit theories of agrammatism.
- Translation and NLP. Mismatched passive systems are a major source of stilted machine translation. Translating Mandarin bei-passives into English without their adversative tone loses meaning.
- Argument-structure theory. Passives are the workhorse construction for testing claims about how syntactic structures encode thematic roles.
Common pitfalls
- Conflating passive with stative. "The door was closed" can be either; tests with manner adverbs or by-phrases distinguish them. German morphologizes the distinction (sein vs werden); English forces context to do the work.
- Assuming Mandarin bei = English by. Mandarin bei is a verb-like marker introducing the agent and carries adversative flavor; English by is a neutral preposition. Direct translation often sounds wrong.
- Calling Tagalog patient voice "passive." Older descriptive grammars do this — but Tagalog has no unmarked active, so the "passive" label misleads. Use "patient voice" or "non-actor voice."
- Overusing passive in style. The passive is a tool, not a sin. Strunk-and-White scolding misses the point: passives are perfect when the agent is irrelevant or unknown. Forcing actives into agentless contexts often reads as awkward — "Someone heated the samples" is worse than "The samples were heated" in a methods section.
- Treating "get" and "be" passives as equivalent. "He was fired" and "He got fired" are both passive in form, but differ in flavor — get-passives often imply unintended or unwelcome events, similar to Mandarin bei.
- Forgetting impersonal passives exist. German and Polish allow passivizing intransitives with no patient at all. The passive is fundamentally about agent demotion; patient promotion is a side effect when there is one.
Frequently asked questions
What does the passive actually do?
It rearranges the mapping between semantic roles (agent, patient) and grammatical relations (subject, object). The patient — the thing acted upon — becomes subject; the agent is demoted to an oblique phrase (the "by"-phrase in English) or omitted entirely. The verb gets special marking. Importantly, the event itself is unchanged — only how the speaker packages it for the listener.
How is the passive different from a stative description?
"The door was closed" is ambiguous: a passive ("someone closed it," dynamic) or a stative ("the door is in a closed state"). True passives entail an action. Tests: add "by Mary" (passive only) or a manner adverbial ("quickly closed by Mary" is fine; "quickly in a closed state" is not). German marks the difference with auxiliaries — werden-passive (dynamic) vs sein-passive (stative). English forces context to disambiguate.
Why does Mandarin bei sound bad with happy events?
Classical bei-passives carry adversative semantics — the subject is affected, often badly. "我被狗咬了" (I was bitten by a dog) is natural; "我被老板表扬了" (I was praised by the boss) was traditionally odd, though modern Mandarin under European influence accepts it more. Languages with adversative passives — also Japanese "indirect" passives — let the passive itself signal that the subject suffers, even if not the direct patient.
Is Tagalog's "patient voice" the same as a passive?
It looks similar — patient is the topic, agent is oblique — but linguists generally don't call it a passive, because Tagalog has multiple equally-frequent voices (actor, patient, locative, benefactive) with no default. In a true passive language, the active is unmarked and basic, and the passive is a marked alternative. In Tagalog, all voices are marked equally, so the system is symmetric. This is the Philippine-type voice system, sometimes called "symmetrical voice" or "focus" system.
Can intransitive verbs be passivized?
In English, no — there's no patient to promote. But German and Latin allow "impersonal passives": German "Es wurde getanzt" (literally "It was danced" = "There was dancing"). The verb is intransitive ("dance" has no object), but the passive still applies, just with no subject promotion — the impersonal "es" fills the slot. This shows passive is fundamentally about agent demotion, with patient promotion as a side effect when there is one.
Why is the English passive so common in scientific writing?
"The samples were heated to 90°C" avoids identifying who heated them — the agent is irrelevant or generic. Passives let writers foreground the patient (samples, results) while suppressing the agent (the experimenter). Style guides since Strunk & White have warned against overuse, but the passive is functional, not bad — it picks topic over agent. The bad reputation comes from politicians using "mistakes were made" to evade responsibility.
Do all languages have a passive?
No. Many languages — including most in the Philippine family and a substantial minority of the world's languages — lack a dedicated passive construction. Some use other strategies: word-order changes (Mandarin can topicalize the patient without bei), middle voice (Greek, Romance reflexives), or the symmetrical voice systems of Austronesian. Siewierska's typological survey (2013, WALS) finds passives in roughly 40% of sampled languages.
